6 Claims.

Shuttle checks or binders for looms are known which are movable by the shuttle when it enters the shuttle-box thus to move to idle or inactive position means for stopping the loom which otherwise (or if the shuttle failed to enter the box) would effect such stopping. Varying conditions in weaving as well as varying conditions in different looms make it desirable to provide a check which can be adjusted so as to have it actuated by the shuttle, and hence move the stopping means to idle position, at different points in the shuttles path of approach to its final po sition in the box. Such a check is the subject of the present invention. It is characterized by an elongated shoe which coacts with the back of the box to stop the shuttle and which is adapted, by force applied at or near its end which adjoins the entrance of the box, to be bent more or less away from said back wall, and by novel adjustable lgo means for determining the extent of and maintaining such bend. The extent of the bend determines, as will appear, the point in the shuttles path of approach to its final position in the box at which the shuttle acts through the check to The. construction is such also that said shoe may be adjusted bodily toward or from said wall of the box, thus to accommodate shuttles of varying sizes.

In the drawing,

30 Fig. 1 is a planof the improved check, with the back wall of the shuttle box and a shuttle shown by dotted lines;

Fig. 2 shows the screw device and bolt and nut, the former in vertical section and the bolt and 35 nut in elevation; and

Fig. 3 is a section on line 3-3, Fig. 1.

a designates the back wall of the shuttle box and b the shuttle in the space of the box formed by said wall and the improved check, which latter is constructed as follows:

l is an elongated body member, being inflexible and having an eye 2 at the end thereof adjoining the outer end of the box to receive a bolt la of the box, the other or entrance end of said member (being the end at the entrance end of the box) being adapted to be limited as to displacement from said wall by another bolt lb of the box arranged to traverse said end as usual. The mentioned stopping means to be moved by 50 the check to inactive position on the shuttle entering the box engages the outer face of member I at the left-hand end in Fig. 1, such means being not shown.

3 is the shoe member consisting of a steel strip 55 of somewhat shorter length than the member I and having about the same width but less thickness than such member. It may be flexed but preferably is not adapted to undergo flexion by either the impact or the pressure of the shuttle.

It extendsle'ngthwise and opposite to the mem- ,;-5 ber .l with one end terminating slightly short of the outer end, but its other end terminating here appreciably short of the entrance end, of said member. U-shaped elements 4 project from the outer face of the shoe member in offset relation to {10 each other lengthwise thereof, being here integral portions of a-metal strip 5 secured by rivets 8 to said face, each such element having a slot 411. These elements are within that lengthwise half of the shoe member which includes its outer end. 15 When in use the shoe member will have generally the form shown by Fig. 1, to wit: So that'from its outer end to a point past the left-hand'element 4 in Fig. 1 its inner face will be lengthwise substantially straight, as at 1, and so that from ,20 such point nearly to its other orentrance end said face will be convex, as at 8,'the remaining or terminal portion 9 of saidface being again straight and about parallel with the face .1. The entrance terminal of the shoe-member has a hole Screws are screwed into the body member and respectively penetrate the slots la in elements 4, their heads being confined between said elements and the strip or body portion of the shoe member; said screws have lock-nuts l2 to bear against the outer face of the body member.

The mentioned supporting structure includes, with the body member, an adjusting screw i3 screwed into said body member opposite the entrance terminal of the shoe member and having a polygonal head l3a for turning it. I l is a bolt and IS a nut thereon for clamping the shoe member and said structure together; in this example, and preferably, the screw device is bored and the bolt penetrates its bore.

Adjustments in several ways are possible. Thus, by rotating both screws H and the screw device in the same direction the shoe member may be adjusted toward or from the supporting structure bodily. Or, the screws being set so that the face 1 of the shoe member is properly spaced from the wall I) of the box to suit the particular shuttle, the screw device may be turned in the .appropriate direction so that the entrance terminal of the shoe member when clamped will have a definite spacing from the supporting structure, involving flexing distortion of said shoe member. Or, the entrance end of the shoe member remaining clamped, the screws ll may be turned in the appropriate direction to space the portion of the shoe member having the face "I away from the supporting structure as required, such also involving flexing distortion of the shoe member. Of course, whenever the screw device is to be turned the clamping means I4, I5 is released.

As the shoe member appears in Fig. l the line of juncture between the straight face 8 and the convex face 9 of the shoe member is at about the arrow 9:. But this line of juncture will shift to the right or left the more or less, respectively, as the shoe member is flexed. The degree of flexion of the shoe member, then, determines the point in the flight of the shuttle where the check will move the stopping mechanism to position to avoid stopping the loom. Thus:

As shown, the shuttle being in the box and holding the checl; at its outward limit or against bolt lb, the mentioned stopping means has been moved to inactive position. When the shuttle is out of the box said means shifts the check around bolt I a as a pivot toward the back wall of the box. On the shuttle now entering the box with the check in the last-named position it will engage and move back the check (and hence shift the stopping means to inactive position) at some selected point in its flight depending on the degree of fiexion which has been formed in the shoe member.

The actual stopping of the shuttle, it will be understood, is effected by the friction incident to contact of the shuttle with the face 1 of the shoe member and the back wall of the box, between which it snugly fits when the check is at its outward limit.

It is important, due to the tendency of the metal of the shoe members of shuttle checks to crystallize, not unduly to weaken the shoe member by holes therein. No such holes, excepting the relatively small hole l0, exists in the shoe member of the present check.

Having thus fully described our invention what we claim is: I

1. A shuttle check including supporting structure itself including an elongated body member and a screw device screwed into and projecting laterally from one end portion of said member, an elongated shoe member beside and extending lengthwise of the body member and having the end portion corresponding to said end portion of the body member bent toward the body member and bearing against said device, means, adjacent to said device, to clamp fast together the shoe member and said structure, and means, removed from said device toward the other ends of the members, to confine the shoe member against angular displacement in a plane cutting the two members lengthwise thereof.

2. The shuttle check set forth in claim 1 characterized by the first-named means penetrating the screw device.

3. The shuttle check set forth in claim 1 characterized by the second-named means comprising headed screws off-set from each other lengthwise of the members and each having a threaded connection with one member and its head confined by the other member against displacement in either direction axially of such screw.

4. A shuttle check including an elongated body member, an elongated shoe member beside and extending lengthwise of the body member and having an end portion bent toward its body member, a screw device having its axis penetrating said end portion and screwed into one member and being abutted by the other member, means, adjacent to said device, to clamp fast together said members, and means, removed from said device toward the other ends of the members, to confine the shoe member against angular displacement in a plan-e cutting the members lengthwise thereof.

5. The shuttle check set forth in claim 4 characterized by the first-named means penetrating the screw device.

6. The shuttle check set forth in claim 4 characterized by the second-named means comprising headed screws off-set from each other lengthwise of the members and each having a threaded connection with one member and its head confined by the other member against displacement in either direction axially of such screw.
